IMPROVEMENT IN ANCHORS.

Specification forming part of Letters Patent No. 164,975, dated J one29, 1875; application filed April 6, 1875.

To all whom it may concern:

Be it known that I, WILLIAM A. OURRIER, of the city of Newburyport,State of Massachusetts, have invented an Improved Anchor, of which thefollowing is a specification:

The object of my invention is to so construct an anchor of four fiukesthat each pair, consisting of two opposite flukes, shall be connectedwith a throat-piece or connecting-bar, which shall be pivoted at itscenter in the crown of the anchor, thus making an anchor that is sure toseize and maintain its hold, easily raised and stowed away, anddispenses with the need of a stock.

In the drawings, Figure 1 is a perspective View of an anchor embodyingmy invention. Fi g. 2 is a longitudinal section of same, taken throughthe center of the shank and crown on the plane of one pair of flukes andthe tLrJatpiece, to which they are joined.

A is the shank, and its continuation forms the crown B. The crown hascut in it'two mortises, a a, at right angles to each other, and at suchdistance from each other, and so related to the crown, as to give thegreatest strength to the latter. They are also of such form and size asto admit and allow the free working of the two throat-pieces orconnectingbars 0 (J, which are pivoted at their centers by the pins orbolts b b, that pass through them and the sides of the mortises, asshown. The flukes D D D D are secured rigidly to their throat-pieces,either welded to them or dovetailed and pinned or bolted, as shown at c,or secured by some equivalent device, so that one of each pair mayberemoved. The mortises may be beveled on both sides of the crown for eachthroat-piece, and front and back of the throat-piece, as shown at cl ande,

so that the throat-piece may have a solid and durable bearing in thecrown, and not strain the pin or bolt by which it is pivoted. At theback of the flukes are the spurs E E E E, of suitable form and locationto insure the proper position of the flukes for grapplingthat is,

by coming in contact with the ground to open out the flukes, so thatthey will present their points to the ground, the throat-pieces swingingon the pivots at b b. Anchors of the common form, with two flukes, musthave what is called a stock-that is, a long cross-piece near the upperend of theshank, to so tip the anchor that the fiukes may take hold. Myanchor needs no stock, as will be readily seen, and when dropped it isat all times in. position for grappling. It will always have two flukesin the ground, and each of them may be lighter than one of an anchorwith two flukes;

hence the whole anchor is lighter by dispensin g with the stock orcross-piece. Should the cable fall on my anchor, on being strained itwill readily slip off, since the flukes will close, and it will presentno obstruction to entangle the cable, as does the common anchor.Moreover, my anchor is more easily and safely iaised to position forcarrying, or shipped, there being no stock, and the flukes closing and.notlstanding out to interfere with any obstruction. It is, therefore,easily taken in, and it may be stowed in the smallest possible space,for one of the flukes may be detached from its ihroatpiece, the latterwithdrawn, and the anchor laid fiat. The fiukes may have any requiredspread by making the bevels of the mortises, as at d and e, of theproportionate angles. The crown about the mortises may be strengthened,as desired.

I claim as my invention 1. An anchor having two throat'pieces orconnecting-bars, O G, pivoted in the crown and working independently ofeach other, substantially as and for the purpose hereinbefore set forth.

2. The combination of the crown B, having the two niortises a a, withthe throat-pieces O 0, each having one or both of the fllukes removable,substantially as and for the purpose hereinbefore set forth.
